An Amazon package of mass ? = 163 kg is released from rest at point A and slides on the frictionless track shown. Point A is ?? = 7.90 ? above the ground. Point B is ?? = 2.50 ? above the ground. Ignore air resistance.

a) Determine the potential energy of the Amazon package at Point A relative to the ground.

b) Determine the speed of the Amazon package at Point B.

c) The Amazon package hits the ground in a perfectly elastic collision. How high does the package bounce into the air (ignoring air resistance)?
